Answer:
b
Explanation:
acceleration is directly proportional to the net force and inversely proportional to the mass
The temperature of the air above it
Velocity B (relative to the A) = Velocity B (relative to the ground) - Velocity A (relative to the ground)
Velocity B (relative to the ground) = Velocity B (relative to the A) + Velocity A (relative to the ground)
Velocity B (relative to the ground) = 7.5 + 5 = 12 m/s
Since both go up in the same direction, we should use the minus sign for relative velocity.
Answer:
The unrealistically large acceleration experienced by the space travelers during their launch is 2.7 x 10⁵ m/s².
How many times stronger than gravity is this force? 2.79 x 10⁴ g.
Explanation:
given information:
s = 220 m
final speed, vf = 10.97 km/s = 10970 m/s
g = 9.8 m/s²
he unrealistically large acceleration experienced by the space travelers during their launch
vf² = v₀²+2as, v₀ = 0
vf² = 2as
a =vf²/2s
= (10970)²/(2x220)
= 2.7 x 10⁵ m/s²
Compare your answer with the free-fall acceleration
a/g = 2.7 x 10⁵/9.8
a/g = 2.79 x 10⁴
a = 2.79 x 10⁴ g
